<p>Phil Gioia grew up an army brat during the decades after World War II. Drawn to the military, he attended the Virginia Military Institute, then was commissioned in the U.S. Army, where he completed Jump School and Ranger School. Not even a year after college graduation, he landed in Vietnam in early 1968¿in the first weeks of the Tet offensive, which marked a major escalation of the war. Commanding a company in the 82nd Airborne Division, Gioia led his paratroopers into the city of Hue for intense fighting¿danger was always just around the corner ¿and the grisly discovery of mass graves. Wounded, he was sent home in May but returned with the 1st Cavalry Division a year later, this time leading a rucksack company of light infantry. Inserted into far-flung landing zones, Gioia and his men patrolled the jungles and rubber plantations along the Cambodian border, looking for a furtive enemy who preferred ambushes to set-piece battles and nighttime raids to daylight attacks.</p><p>Danger
